Use a gcode pre-analysis to provide better print time estimation
Generate highly accurate gcode printing time estimations using advanced gcode analyzers combined with the printing history.
PrintTimeGenius provides estimates that are accurate to within just minutes, sometimes even seconds! It can even account for the time to heat up the nozzle/bed. It uses an algorithm to calculate the print time remaining while running so that even if the original estimate was wrong, it will still converge on the correct one.
PrintTimeGenius uses the estimates embedded in your gcode, put there by slic3r or cura. It also runs a Marlin or Smoothieware simulation to provide line-by-line accuracy, often accurate within 0.2% of actual print time.
